Cutback Bitumen
|
Cutback Bitumen is a type of dissolved bitumen. Solvent oils such as Gasoline or Kerosene are used to change bitumen into dissolved bitumen or liquid pitch. During consumption process, the solvent oil evaporates and the bitumen resides to obtain the desirable adhesion. Cut back grades are: Slow curing (70-250- 800-3000 ), Medium curing (0-1-2-3-4-5-30-70-250-800-3000) and Rapid curing (30-70 -250-800) |
